摘要：

One of the major degradation involves the electrocatalyst, including the corrosion of the carbons used as catalyst supports which leads to changes in the catalyst layer structure. These changes in the catalyst layer structure lead to reduced kinetics and to mass transport limitations. The catalyst layer degradation is due to a combination of degradation mechanisms, including localized effects and depends upon operating conditions
